[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 MnsJEvn/  
>a!/QMh  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： Z, zWuE3  
enableservice('AutomationServer', true) . oF &Ff/[  
enableservice('AutomationServer') e8>})  
VZp5)-!\  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 guq{#?}

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： [`#CXq'  
1. 在FRED脚本编辑界面找到参考. lK?uXr7^  
2. 找到Matlab Automation Server Type Library :T^a&)aL%  
3. 将名字改为MLAPP }/0X'o

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 ^H p; .f.

2. 移动探测面对于前一聚焦面的位置。

3. 在探测面追迹光线 >2y':fO  
4. 在探测面计算照度 Q

5. 使用PutWorkspaceData发送照度数据到Matlab euK5pA>L  
6. 使用PutFullMatrix发送标量场数据到Matlab中 oM

7. 用Matlab画出照度数据 fF!Yp iI"  
8. 在Matlab计算照度平均值 sf:,qD=z  
9. 返回数据到FRED中 ^rB8? kt
